Development of an Advanced Fatigue Model of a Cement-Treated Base Material Based on Continuum Damage Mechanics

Cement-Treated Base (CTB) is a mixture of a road base material, a prescribed amount of cement, and water. In doing this, the performance of road pavement structure can be improved. This research aims to achieve improved CTB characterisation and design procedures. The characteristics of CTB material were examined through conventional and sophisticated testing platforms. Accordingly, the new mix design framework and fatigue damage evolution model were developed based on the test results of this research
